Yes, February 29, 1984. Note that the original Earth-One Jason Todd officially became Robin that same month in Batman #368, so he was VERY "new to the job" when introduced to Wonder Woman in "For the Man Who Has Everything". But he proved to be a quick study -- figuring out how to defeat Mongul with a potted plant!

That was probably Pre-Crisis Jason's finest hour. I still hate what they did to him afterwards...
